Hello Sir..I found the videos very conceptual and insightful and I'm thoroughly enjoying solving examples after learning the concepts but my question here is a little off the topic if you don't mind me asking...I wanted to know what is the usual trend of number of questions asked from different sections of maths like algebra, Number system, arithematic, geometry..I am getting different answers on different pages on the internet..it is really essential for me to know this given the very limited time left in CAT so as to be able to focus more on those topics whose weightage is usually more. Kindly assist.

Hey Amulya. So, I think I have a better idea for short term prep than going by chapterwise weightages. PM me. We'll discuss. 🙂

ok...thanks sir
sir, not able to understand what exactly non negative solution means, do we need to find only the positive integer values of x,y and z which satisfies the equation?

Hi Avnish, Positive integers: 1, 2, 3, ........infinity. Non-negative integers: 0, 1, 2, 3, ........... infinity. Hope this'll clear the doubt. 🙂
sir in the first example...the answer is -1.. tell me how radha can pay -1 for one apple 6 oranges and 9 guava. since -1 is invalid in terms of rupees

Hello Ajeet. Your observation is correct. And of course one cannot make negative payments. Just that, I meant to provide an example of context in which this type of question from linear equations can be asked. The equations don't actually pertain to 'shyam' or 'radha' buying oranges. If they did, we couldn't have accepted '-1' as a solution. But yes, my bad for not making that abundantly clear. And I hope that the doubt is clarified now. 🙂

okay...sir... u mean that example was jxtt for making us understand ....... and u caught that equation accidentally...not intentionally..😅

No, I meant that the 'Shyam-Radha' example was taken impromptu, to provide relatable context. The equations were of course planned ahead.
